RALEIGH, N.C. — Johnny Boychuk sat out Saturday night’s game with an upper-body injury, leaving the Islanders without their two regular right-handed defensemen.

Boychuk played 21:22 in Friday night’s 5-2 win over the Panthers in Sunrise, Florida, but he took a hard hit from a pair of Panthers in the third period and skated away slowly.

With Travis Hamonic (knee) already sidelined and missing his third straight game Saturday night, the Isles turned to Scott Mayfield to play his fourth game of the season. Adam Pelech already was in the lineup in place of Hamonic.

Mayfield was called up from Bridgeport on Thursday and was a healthy scratch against the Panthers. He’s been involved in the offense in his limited NHL work this season, with his assist on John Tavares’ game-opening goal Saturday night giving him four points in his four Isles games. He had only one point in 11 games during the previous two seasons.

Jack Capuano said that one of his forwards was a bit banged up, so Stephen Gionta dressed for warmups, but there were no changes there. Shane Prince and Gionta were the forward scratches.

Greiss back-to-back again

Thomas Greiss made his sixth straight start and played on consecutive nights for the second time in as many weeks.

“It’s not that [J-F] Berube can’t do the job, but Greiss has been playing well,” Capuano said before Saturday night’s game. “We’re going with that hot hand.”

Carolina goaltender Cam Ward made his 19th consecutive start Saturday night.

With the Islanders playing Monday afternoon in Boston, there is a definite chance that Berube — who still hasn’t played since becoming the backup goaltender when Jaroslav Halak was sent down on Dec. 31 — will get a start soon.
